# Start a catalog experience thread \[write\]

`POST /threads/experiences`

## Request

- Base URL: `https://api.agentsky.dev/v1`
- URL: `https://api.agentsky.dev/v1/threads/experiences`
- Auth: HTTP bearer

The same Mac/web experience owner and turn admission. Personal API key with write scope, using its verified workspace or X-Universe. Reuse requestId on retries: a failed admitted turn retains its existing playgroundId rather than minting a second thread. No body workspace override is accepted.

## Request body

- object
  - `experience` string, required
  - `text` string, required
  - `requestId` string, required
  - `timezone` string

## Response `201`

Started thread

- object
  - `playgroundId` string, required
  - `sessionId` string, nullable, required

## Other responses

- `404`: Error — { error: { code, message } }
- `409`: Admission failed after a thread was retained; response includes playgroundId for recovery
- `422`: Error — { error: { code, message } }
- `default`: Error — { error: { code, message } }

## Changes
